March 6, 2006

Alan, Colin, Tom, Maduna, Tom, Bryan, Jeff, Charlie

• Alex did the mojo and we now have DBI/DBD on the pmp. Next is finish transactions and cleanup code.
• Jeff emailed ARM about the watchdog timer, no word yet. Charlie will look at the BIOS setting.
• Colin will look into how to do damping of the direction and speed readimg.
• Colin will fix the graphs including the date ranges.
• Breadboard Wed at 1p
• Rainguage is working and recording data, congrats Tom and Maduna. Mounting, reseting discipline and technique, and display elements are all that's left.
• Windchill calculation, both the Davis interface firmware upgrade and the new formula. Bryan.
• X10 systems. Tom waded into this and found some stuff. Heyu. Alan will get a serial controller.
• Use WECI tower for annenometer mountings.
• GPS.

February 13, 2006

Alan, Jeff, Bryan, Colin, Maduna, Tom, Alex, Charlie

• C to read raw value, Perl (called from cron) to buffer to file and send to server every N times, server inserts into database and returns ACK to Perl.
• Use TV antenna for the tower.
• Check the TS-5600 library.
• Watchdog timer (Jeff)
• Rain gauge (Tom, Maduna)
• GPS (Alex, Jeff), solar radiation (Colin, Maduna)
• Alan's applications - 1) small machine that does temp and displays via http and send X10 commands out the serial interface with X10 switches and dial-up and ethernet interfaces. 2) robot to go in a house under remote control, B/W (or color) video, up stairs, 30 minute, budget of about $2000.

February 6, 2006

Tom, Colin, Alex, Maduna, Jeff, Bryan, Alan, Charlie

• Do we have a calibration/accuracy problem WRT wind direction? Rest of the stuff listed below (Colin, Alex, Bryan)
• GPS (Alex and Jeff)
• Watchdog timer (Jeff)
• Rain gauge, try plugging into the interface and testing (Maduna, Tom)

January 30, 2006

Colin, Alex, Tom, Jeff, Bryan, Maduna, Alan, Charlie

• Laid-out the architecture of the quark-pmp-wind components and the interfaces.
• Look at the TS-5600 library interface for reading ports rather than /dev/...
• Put together a circuit based on a voltage regulator supplied by the board power port.

Organization Meeting - January 11, 2006

Alex, Bryan, Colin, Tom, Maduna, Jeff, Charlie

• Regular meetings this semester will be on Monday at 12p in the Dennis 4th lab.
• Wind speed and direction - data aquisition/data transfer/packaging/deployment (Colin, Jeff, Alex, Bryan)
• GPS - data aquisition/data transfer/packaging/deployment/ntpd/clients (Alex, Jeff)
• Rain gauge - data aquistion/data transfer/visualization (Tom, Maduna)
• Solar radiation - data aquistion/data transfer (Colin, Maduna)

To Do

Last updated 2006-02-05

• Fix wind chill calculation, use new formula
• Figure-out watchdog timer on PMP
• Backup on PMP - just needs to be put in cron (Tom)
• Wind data for this area (Mary)
• Problems with direction - determine input voltage and calibrate to that (Alex and Colin)
  • Stable voltage needed, e.g. when WiFi card is removed voltage fluctuates. Measure at start and end, if equal than ok.
• Porting wind speed and direction software and setup to pmp, made some progress (Mary, Alex, Colin)
  • Speed working now, using sigalarm(), need a resistor? DIO for power.
  • Direction isn't working yet.
  • Next week on roof?
  • Two weeks in field?
• Sleep and wake on pmp1 with watchdog timer (Mary)
• Weather Cam is working again, cluster camera to be setup in D209.
• RP&L Weather data, contact Gus Duke. Indiana American Water has a link which she sent. (Mary, Charlie)
• Rain guage, Mary has worked on it but it's not working. (Mary, Charlie)
• Solar radiation sensor, continues to make progress, conversion and data comparison (Colin)
  • How to set angle/calibration.
• GPS setup with time server (Tom)

Hardware:

• PMP
  • Technologic Systems TS56000 single board computer running Linux off a SANDisk.
  • URL for the board and documentation
  • To Do
    • Port threaded anemometer code, change code to use local analog/digital inputs
    • Setup NFS mounting of / on the pmp from proto
    • Test analog and digital inputs
    • Setup and test WiFi interface
    • Test and document backup and recovery procedure
    • Identify and recover missing files from SANDisk
    • Design and implement data collection, sleep, and data transfer functions

• Anemometer
  • The Wind direction sends an analogue number.
  • The wind speed is the number of pulses per 2.25 second interval. The number of pulses is the windspeed in MPH.

• We are using a Digi PortServer TS 2, SN=V40611264
  • URL of the documentation

• Rain guage:
  • Sends a pulse every time the cup switches.
